The tail section of the exhaust pipe is part of the exhaust system, and it is also the third stage of the exhaust system. The structure is basically the same as that of the middle section. The original specification of the exhaust pipe material is also galvanized iron. It is made of plate and iron pipe, and the inside is also composed of back pressure partition and silencer cotton.

The high-performance tail section exhaust pipe casing is also made of durable and heat-resistant stainless steel material. The inner part is smoothly discharged by the rotary back pressure baffle. The stainless steel sound-absorbing cotton is wrapped with fiberglass silencer cotton, which can be reduced. At the same time of exhaust resistance, the engine maintains a reasonable low-speed torque output, and greatly prolongs the service life of the muffler cotton, so that the exhaust pipe maintains a stable exhaust smoothness while maintaining a normal muffling ability for a long time.

In recent years, the titanium alloy tail section exhaust pipe has not only high temperature resistance and durability, but also the exhaust efficiency is greatly improved due to the increase of the exhaust gas temperature, and the titanium alloy tail section exhaust pipe is light in weight and high in material strength. Compared with the stainless steel tail section exhaust pipe of the same specification, the weight can be reduced by 40% and the pipe wall can be 30% thinner. However, due to the difficulty in processing titanium alloy materials and the need for laser welding, the cost is nearly double that of stainless steel products.
